>>How many tube rectifiers have you listened to?<<

None.

>>Which one would be easier to fix if it blows, a tubed rectifier, or ss one?<<

Neither as both the tube or SS rectifier would have to be replaced. It'd be easier and cheaper to source a SS rectifier though.

>>just what IS your experience with rectifiers, tubed or otherwise<<

No hands-on experience with tube rectifiers. I played with plenty of SS rectifiers in tech school and a more at work when I fixed weather radar units.

>>>The only good thing I can think of for using a tube rect. is slow start up<<<

Let me rephrase: The only electrical advantage of a tube rectifier over a SS is that it provides slow start up for the HV supply. The disadvantages of a tube rectifier (electrically speaking, not sonically) is that you need another filament supply (more energy usage) and a power trannie with more voltage output (at the same current) as the tube rectifier gobbles up alot of power supply voltage (energy) in the rectification process. The tube rectifier is nowhere near as efficient as a SS rectifier. This is an electrical fact that one does not need direct experience with. I cannot comment on what tube rectification does for sonics as compared to SS rectification. It was not my intention to imply that SS diodes are sonically superior to tube rectifiers.
